MICROWAVE HEATER

摘要

A high-frequency microwave heater for achieving desired cooked state of an object to be heated suited for the kind of the object when a grill menu is selected and heating the object with an improved heating efficiency. The microwave heater comprises a heating chamber where a heating pan on which an object to be heated is placed is disposed detachably, microwave generating means, a waveguide for transmitting a microwave from the microwave generating means, a rotary antenna for emitting the microwave from the waveguide into the heating chamber, drive means for rotatingly driving the rotary antenna, and operation section for selecting a grill menu for heating the object placed on the heating pan or a warming menu for heating the object without using the heating pan, and control means for controlling the drive means according to the output signal from the operating section. The control means controls the drive means so as to vary the direction of the portion of strong radiation directivity of the rotary antenna according to the output signal from the operation section.
